Second Class: Co-valent And Ionic Bonding

In this class we looked at the basic part of basic chemistry: bonding of atoms.  The first two that we study are: Co-valent and Ionic bonding.  Co-valent bonding is where valence electrons are shared between the two molecules that are bonded share the electrons to complete each others outer shells.  In ionic bonding some of the molecules will give up their valence electrons to drop down to a complete electron shell and become stable.

These different types of bonds dictate what atoms can bond with other atoms and in what way they will do it.

First Class: Dancing Milk

In the first class of Honors Biology we created an experiment to explain why milk with food coloring "dances" with a drop of soap.

First, Eddie and I hypothesized that the intensity of the reaction was based off of the amount of fat in the milk.  To test our theory we made the milk a variable and tested different types while keeping the soaps a constant.  The different milks we used were whole, 2%, and skim.  Using the same soaps in these three different milks we found that whole milk had the fastest and longest lasting reaction while skim had the least.  To make sure that this result was caused from the difference in milk we used Dawn, Sun, Ajax (bleach), and Palmolive Orange dish soap in all 3 and found that the different soaps made little to no difference in reaction.  From this we concluded that the amount of fat in the milk did affect to what extremity the food coloring would "dance."
